Olsoning 

The act of being a pedophile, scam artist, and overall piece of shit, all in one.

That Nick kid is Olsoning so hard. His existence kills brain cells of anyone within a 3 mile radius.

Olsoning 

To reach a level of intoxication in which gravity increases by a minimum of 50% and hallucinations develop in which one is surrounded by "bitch ass niggas." Speech is inhibited and condensed down to vulgar language, all of which is slurred to beyond comprehension.

"Yesterday I got so drunk I was just rolling around on the floor telling my roommate to fuck off."
"Dude, you were totally Olsoning."

Olsoning 

When you create a kick ass group and people get jealous and make up lies and talk shit.

Tyler is baby and is really jealous of that guys Olsoning skills so he talks shit on the internet.
